Pathogen promotes insect ovarian development by inducing a dual role of host ATPSyn-β

open access: yesCommunications Biology
Candidatus Liberibacter asiaticus (CLas), a pathogenic bacterium causing citrus Huanglongbing, forms a mutualistic relationship with the Asian citrus psyllid, Diaphorina citri. However, the underlying molecular mechanisms remain unclear.

Ecdysis Triggering Hormone Signaling (ETH/ETHR-A) Is Required for the Larva-Larva Ecdysis in Bactrocera dorsalis (Diptera: Tephritidae)

open access: yesFrontiers in Physiology, 2017
Insects must undergo ecdysis for successful development and growth, and the ecdysis triggering hormone (ETH), released by the Inka cells, is a master hormone in this process. In this study, we determined the sequence of the ETH precursor and receptors in

The use of mixed species cropping to manage pests and diseases – theory and practice [PDF]

open access: yes, 2002
This paper was presented at the UK organic research 2002 on behalf of colloquium of Organic Researchers (COR). Mixed species cropping is often perceived as a viable tool to increase on-farm biodiversity in organic agriculture and is a potentially ...

Molecular crosstalk via exosomes in lung cancer progression

open access: yesInterdisciplinary Medicine, EarlyView.
“Molecular and theranostics roles of exosomes in Lung Cancer.” Abstract Exosomes play a critical role in lung cancer metastasis, facilitating tumor progression through intercellular communication between cancer cells and the tumor microenvironment. These nanosized extracellular vesicles carry bioactive molecules such as proteins, nucleic acids, and ...

Involvement of Met and Kr-h1 in JH-Mediated Reproduction of Female Bactrocera dorsalis (Hendel)

open access: yesFrontiers in Physiology, 2018
Juvenile hormone (JH) prevents metamorphosis during insect larval stages and promotes adult reproductive processes. Krüppel-homolog 1 (Kr-h1), a zinc finger transcription factor assumed to be induced by JH via the JH receptor methoprene-tolerant (Met ...

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Raman Signature of the Wings of the Globe Skimmer Dragonfly: Pantala flavescens

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman spectroscopy is used to confirm the presence of aliphatic and aromatic hydrocarbons and related derivatives including aldehydes, halides, alcohols, acids, esters, and phenols on the wings of Pantala flavescens. The analysis indicates that wing‐surface lipid composition is largely consistent across the three main ecological zones in Ghana. Notably,

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).
